TOOL-HEATER.

Specification of Letters Patent. Patgntgd 091 1919,

Application filed May 17, 19-19. Serial No. 297,950.

To all whom it may concern Be it known that I, ERNEST Junnenns, a citizen of the. United States, residing at Taylor, in the county of Williamson and State of Texas, have invented certain new and useful Improvements in Tool-Heaters, of which the following is a specification.

This invention relates to tool heaters, and more especially to those adapted to heata soldering ironby gas; and the object of the same is to provide a gas heater in which steam is directed into the burner and admixed with the gas to increase the heat beneath the tool.

Another object is. to provide means for cutting off the steam when the water gets low and notifying the operator.

Another object is to utilize the heat from the burner to generate steam.

Other objects will appear in the following specification and claims. In the drawings Figure l is an end elevation of this device complete, partly broken away.

Fig. 2 is a front elevation thereof with the boiler partly broken away.

Mounted on a base 1 is .a hollow upright shell or casing 2, preferably cylindrical and open at its front as seen in F 2, the front opening being crossed by tool holders, as indicated at 3, so that a soldering iron may rest thereon. Within the shell are transverse partitions 4 having central openings 5 preferably surrounded by flanges 6 to support the head of the tool when its shank or handle rests upon therack 3, as indicated in dotted lines in Fig. 1. Two of these partitions .and openings are shown in the drawings but I would not be limited in this respect. The openings are preferably along the axis of the shell 2, and beneath the lowermost is a burner 7 herein shown as intended to burn gas which is led along the pipe 8 from a suitable source, and the heat of the flame passes up through the openings and is directed against the heads of the several tools. A cook or key 9 beneath the burner may be reached through the open front of the shell, so that the gas can be controlled or shut off.

Disposed preferably transversely across the upper end of the shell is a tanker boiler 10 whose top preferably has a. filling openingv and cap 11 at one end and a steam dome 12 at the other, the dome itself preferably having a safety valve 13 in its top. From with- 'no harm will be done.

burner generatesheat too rapidly, excessive in this dome a pipe 14 leads downward through ahcontrol valve, 15 to,.ajet, nozzle 17, normally directedupward intoone of the air .inlets in the Bunsen burner 7 if such be employed. ".The pipe 14 is-bentas. ,seenuin the drawings and stands I normally within a side opening 16withinthe shell 2, butit is possible to swing this pipe forward .as shown in. dotted. lines in Fig.. l, at", which time its jet 17 is brought rawayxfrom the.

pass a bolt 21, its rear end carrying a weight 22. the body of theboileris perhaps half .filled with water as seen in Fig. 2, it-lies upon the upper end of the shell 2 in' normal position The weight is of such sizethat when and the pipe hangs from theboiler: and

passes through the opening as shown. Now heat rising from theburner heats the water in the boiler and generates steam, steam rises into the dome 12; and escapes-down the pipe 1.4 asalreadydescribed, and eventually the water will be consumed" so that itgfalls within the boiler. When itbecomes dangerously low, the weight. 22 overbalances the boiler which is therefore rockedeon its hinges 20 to the dotted position shown in Fig. 11 andthe lower end .of thep'ipeand-its jet are thrown forward and'notice is given to the operator inspite of himself. .Also the boiler tips back out of theadirect-lineof heat rising from the burner 7 and. alt-of which neednot now escape-throughthe front opening in the shell. .The result 1-iszthat Of course if the steam may escape through the Valve--13. The flow of steam throughlthc jet 17 is; con.- trolled by the hand valve or control valve 15. Thus when the, device is Juse,-,-the

jetof steam is supplied to the gas as it is burning within the burner, and a very hot flame results.

The foregoing description and the drawings have reference to whatimay .be-con- 'sidered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a tool heater, the combination with an upright shell, tool racks therein, and a gas burner at the lower portion of the shell; of a water boiler disposed across the top of the shell and having a steam dome, a pipe leading from a high point in said dome through the shell, and a jet on the pipe directing steam into said gas burner, as described.

:2. In a tool heater, the combination with an upright cylindrical shell open in its front and at one side, tool racks within said shell, and a gas burner at the base of the shell beneath said racks; of manually controlled means for supplying gas to said burner, a boiler across the top of the shell, a pipe leading from the steam space in said boiler through the side opening in the shell, manually controlled means for regulating the flow of steam through the pipe, and a jet nozzle on the delivery end of the pipe directed toward said burner, as described.

3. In a heater of the type described, the combination with an upright shell open down its front and one side having an opening communicating with the front opening, a gas burner within the lower end of said shell, and means for supporting tools within the shell above said burner; of a water boiler movably supported on the upper end of the shell whereby steam may be generated by the heat of said burner, means for moving theboiler when the water therein becomes low, a pipe leading from the steam space in the boiler through the side opening in the shell, and a et nozzle on the pipe directed into said burner.

l. In a heater of the type described, the combination with an upright shell open down its front and one side having an opening communicating with the front opening, a gas burner within the lower end of said shell, and means for supporting tools within the shell above said burner; of a water boiler lying across the upper end of said shell, a

hinge connecting the boiler with the rear of the shell, a pipe leading from the steam chamber in said boiler through the side opening in the shell and having a nozzle directed into said burner, and a weight carried by the rear of the boiler and adapted to tilt it when the water becomes low.

5. In a heater of the type described, the

combination with an upright shell open down its front and one side having an opening communicating with the front opening, a gas burner within the lower end of said shell, and means for supporting tools within the shell above said burner; of a water boiler lying normally across the top of said shell, a hinge connecting the boiler to the rear of the shell, a steam dome on the boiler, a pipe leading from within said steam dome down alongside the shell and bent inward through the side opening thereof and directed toward said burner, a bolt extending transversely through the boiler, and a weight on the rear end of the bolt adapted to tilt the boiler to the rear when the water becomes low and throw the bent end of said pipe out of the side opening and against one of said tool racks.

6. In a device of the character described, the combination of a burner having a gas supply, a tank carried above said burner, means for conveying steam from said tank to said burner, and means for automatically removing the tank from its normal position when the water level in the tank has become dangerously low.

7. In a heater of the character described, the combination of a burner including a gas supply, supporting means surrounding said burner, a tool holder carried above said burner and extending beyond the supporting means, a tank hinged upon said supporting means above said burner, a pipe leading from said tank to said burner for supplying the same with steam, and said tank being adapted to swing to one side when the water level thereof decreases below a predetermined point, whereby said pipe will be swung out into engagement with the tool holder to limit further swinging movement of the tank.

8. In a heater of the class described, the combination of a burner including a gas supply, a supporting means surrounding said burner, a tank hinged upon the upper end of said supporting means, a bolt eX- tending through said tank and having a weight at its outer end, a pipe extending from said tank to said burner, whereby steam generated within the tank will be directed to said burner, although at a predetermined time said weight will swing said tank to one side, as described.

In testimony whereof I afiix my signature in presence of two witnesses.
